Come next March, Petco Park will have another home team: Bumble Bee Foods.

The tuna company is moving its corporate offices into the historic Showley Brothers Candy Factory building, located on the northeast corner of the Park at the Park.

The building, erected in 1924, was moved 280 feet from its original location on 8th and K streets in 2003 to make room for the new baseball stadium. As part of the deal, the Padres ownership group paid to move it and agreed to preserve the building.

The building is one of three historic structures incorporated into the ballpark’s design, with the most notable being the Western Metal Supply Co., which includes bars, restaurants, the Padres team store, and the left field foul pole.

Bumble Bee signed a 12-year-lease with the O’Malley-Seidler group, which separately owns the building and the Padres. Bumble Bee plans to move its 140 employees into the 28,000-square-foot building March 1. In the meantime, it must do about $2.5 million in upgrades.

“There’s no electricity, no plumbing and no air conditioning,” said Chris Lischewski, chief executive of Bumble Bee. “We’re starting with an empty shell.”

The building has been vacant for about a decade, before it was moved to make room for the stadium.

Bumble Bee signed the lease four months ago, but the state had to approve plans to rezone the first floor of the structure to office-use, which it did on Sept. 9.

The three-story building’s first floor had been zoned for retail-restaurant use, but that would prove difficult when the Padres host their 81 home games a year and close their gates to the general public, said Erik Greupner, the team’s senior vice president and general counsel. The team’s concessionaire has exclusive rights to the Padre games, so the business couldn’t operate when the fans are there without another deal. There’s also no entry to the building without being inside the stadium grounds.

Bumble Bee is in negotiations to open a coffee shop and retail store in the adjacent Diamond View Tower. Lischewski said he hopes to see movement on that in about a month.

For now, Bumble Bee will put its own mark into the three-story Showley Building, making the interior more of a modern, urban design with an open setting. It will be a change for the employees, who are now in a nine-story modern tower in Kearny Mesa.

Bumble Bee dates back to 1899, when seven canners formed the Columbia River Packers Association in Astoria, Ore. Bumble Bee became a label of the company in 1910. In 1966 Bumble Bee Seafoods Inc. formed, and in 1977 it expanded in San Diego, now the site of its corporate headquarters.

The Showley Candy Co. started before the building broke ground. In 1905, B. Guy Showley and J. Ray Showley started the Showley Brothers Candy Factory, operating it out of the former Montezuma Hotel at Second Avenue and F Street. Some of their candies included the “5-cent Cluster Ruff,” jelly beans and taffy.

As the company grew, it moved into a larger space on Eighth Avenue, but that building burned down in January 1924. That’s when the Showleys built the factory at Eighth and K, which housed the company until 1951, when it was liquidated by Guy R. Showley, son of B. Guy Showley. In 1960, he sold the building.

It was a clothing warehouse until 1982, when developer Lin Martin converted it to live-work loft housing. In 1999, the Centre City Development Corp, the former city redevelopment agency, bought it under eminent domain for $3.5 million, and then deeded it to then-Padres owner John Moores’ real-estate group as Petco Park was developed.

The third historic building on the Petco Park site, the Shieffer and Sons building, houses the South Paw Social Club. It is owned by Capital Real Estate Ventures, not affiliated with the Padres ownership group.
